Definitions
- the invention relates to a tubular food casing based on cellulose with a coating present on its inner surface to improve the peelability of the casing from the contents and to the use of the food casing.
- the invention relates to peeler casings which are used for sausage meat and scalded sausage types and which provide very good peelability on automatic peeling machines which operate at high speed.
- Food casings are also suitable for narrow casings and wreath casings, which are used, for example, for smoked meat sausages and coarse meat sausages.
- Cases of the generic type are already known from EP-A-109 611 and have on their inside a coating of a mixture of a water-soluble cellulose ether, a wax and an oil.
- a casing of the same type known from DE-A-34 47 026 also contains cellulose ether and wax in addition to a chromium-fatty acid complex compound and a dialkylpolysiloxane in an internally applied coating. All known formulations for improving the peelability have relatively complicated compositions, and they leave something to be desired in terms of their effectiveness, particularly in the case of problematic filling goods.
- edible casings based on polysaccharides such as alginic acid or alginate, chitosan, pectin, starch, furcellaran, carrageenan and agar are also known (EP-A 0 400 484). These shells dissolve in hot water.
- the edible casing can be made heat-sealable by a layer of water-soluble protein applied on one or both sides.
- the food casing according to the invention is preferably an artificial sausage casing, in particular a water-free sausage casing, which is suitable for scalding, smoking and automatically peeling small scalded sausages.
- the special coating on the inside shows reduced adhesion between the inner wall of the casing and the filling material, which is typical for small and medium-sized casings and coronary but also for large-caliber casings, especially when the filling material is a sausage meat for cooked sausages, such as frankfurter sausages, or like hunting sausages , Ham, meat sausage, mortadella, yellow sausage or Lyoner, but also for smoked sausage and raw sausage such as coarse mettwurst, the latter being produced in particular in curved or ring-shaped casings made of cellulose without fiber reinforcement.
- the food casing consists of a carrier tube based on cellulose and the coating provided on its inner wall to improve the peelability of the casing from the filling material.
- the base material for the carrier tube is cellulose (cellophane, regenerated cellulose, cellulose hydrate) and is produced in the usual way as a seamless tube by coagulation and regeneration, preferably from viscose solution. It is also possible to use hoses with an adhesive seam, which are produced by folding a web and connecting the edges (EP-A-0 050 702, EP-A-0 058 240).
- a carrier tube made of cellulose with a fiber reinforcement, which is embedded, for example, in the form of a paper web in the wall of the carrier tube, is used for the use of the casing for producing sausages of the large caliber type of cooked sausage.
- ring casings which have no fiber reinforcement
- the curvature is produced, for example, by one-sided expansion of the hose during its manufacture, but other methods are also known (US Pat. Nos. 2,136,566, 2,925,621, 3,679,435, 050502 EP).
- the food casing can be used as a flat tube for filling with contents. Ruched tubular casings, so-called caterpillars, can also be produced, using conventional gathering devices (US Pat. No. 3,988,804). It has been shown here that the inner coating not only achieves an improved separation effect between the filling material and the inner wall of the casing, but that there are also additional advantages when winding, storing, gathering and processing. The inner coating ensures that the hoses wound on a roll do not stick or stick. Even casing sections do not stick together during long storage and can be opened without problems before filling with sausage meat, especially on automatic filling machines. Furthermore, the hoses are particularly slippery and soft and can therefore be gathered easily.
- the coating contains alginates, alginic acid and / or chitosans.
- Alginates are salts of alginic acid, especially alkali or alkaline earth salts.
- Alginic acid itself is a colorless, carboxyl group-containing polysaccharide with an average molecular weight between 100,000 and 240,000.
- alginic acid consists of 1,4-glycosidically linked D-mannuronic acid units with occasional insertions of ⁇ -glycosidically bound L-guluronic acid units.
- Alginic acid as such is a natural product and finds in abundance in the brown algae of the sea.
- the chitosans are a compound group that is derived from naturally occurring chitin. They result from deacetylation and partial depolymerization of chitin with the help of strong alkalis. Chemically, they are ⁇ -glycosidically bound poly-N-acetylglucosamines, the acetyl groups of which are saponified to a greater or lesser extent by the action of the strong alkalis.
- the chitosans have an average molecular weight of approximately 400,000.
- the application amount of the hydrophilic active component (s) is, according to the invention, in the range from 5 to 100 mg / m2, preferably in the range from 10 to 70 mg / m2, based on the dry weight of the casing.
- the application takes place from an aqueous coating composition with a concentration of the active components in the range from 0.5 to 4.0% by weight, preferably in the range from 1 to 3% by weight, based on the total weight of the preparation solution.
- the coating of the food casing according to the invention preferably contains further lubricants, gathering aids and release agents as additives.
- oils are particularly suitable for this purpose, for example natural oils such as olive oil or rapeseed oil or synthetic mono-, di- and triglycerides, paraffin oils, silicone oils and / or Waxes.
- Preferred waxes are acid waxes based on raw montan wax. They are available, for example, under the name Hoechst-Wachs, type E, X22, F, KP 301, KPS, KSL, KSS, KST, KFO, U, BJ or RT.
- the KPS type is preferably used, an ethanediol ester of montanic acid.
- the additives are added to the aqueous coating composition in amounts of 0.5 to 30% by weight, preferably 1 to 5% by weight, based on the total weight of the aqueous preparation solution.
- the usual emulsifiers e.g. Alkyl sulfonates, alkyl aryl sulfonates, alkyl sulfates, alkyl aryl sulfates or nonionic emulsifiers such as ethoxylated alcohols or amines are added.
- Monofatty acid esters or polyhydric alcohols such as sorbitol monoesters or alkanediols such as 1,2-propanediol are also suitable as emulsifiers.
- the emulsifiers are used in amounts of 5 to 50% by weight, based on the weight of the preparation solution. It has surprisingly been found that in particular the alkanediols, and here preferably 1,2-propanediol, have an additional stabilizing effect on the casings, in particular on the graffed casings (caterpillars), preferably on those which are made up of a more labile basic material.
- Preparation solutions which, in addition to alginate, alginic acid and / or chitosan, contain both an oil and a wax have proven to be particularly suitable for types of peelings.
- the food casing according to the invention is produced by the usual methods for producing food casings, in particular sausage casings, based on cellulose, which can be easily peeled off from the filling, in particular from the sausage mass.
- the inner coating is applied to the inside of the tubular casing in the usual way, for example by pouring a coating liquid into the tubular casing (GB-A-1 201 830, US-A-2,901,358, DE-A-28 01 038, DE-C-30 12 250) or by spraying the coating liquid into the tubular casing during the shirring process, e.g. through the hollow shirthorn (US-A-3,451,827).
- the application temperature is usually equal to the ambient temperature, i.e. it is around 15 to 30 ° C.
- the filling of the coating liquid into the tubular casing expediently takes place during the manufacture of the tubular casing, for example after the cellulose hydrate gel has been precipitated from viscose and before drying.
- the casings according to the invention are filled with sausage meat, scalded and smoked during their intended use, the casings can be removed completely easily on automatic peeling devices.
- the coating according to the invention has proven itself in practice both in the case of cellulose casings and in the case of fiber-reinforced cellulose casings.
- the resulting coating composition is filled into a 23 mm caliber peeling gel tube and then dried, moistened and inflated and then gathered into caterpillars.
- the caterpillars are filled with sausage meat, cooked, smoked and automatically peeled. When peeling, all casings could be removed without any problems, no jelly deposits occurred.

Abstract
Description
Die Erfindung bezieht sich auf eine schlauchförmige Nahrungsmittelhülle auf Basis von Cellulose mit einem auf ihrer inneren Oberfläche vorhandenen Überzug zur Verbesserung der Abschälbarkeit der Hülle vom Füllgut und auf die Verwendung der Nahrungsmittelhülle. Insbesondere bezieht sich die Erfindung auf Schälerhüllen, die für Würstchenbrät und Brühwursttypen verwendet werden und auf automatischen Schälmaschinen, die mit hoher Geschwindigkeit arbeiten, sehr gute Schälbarkeiten liefern. Darüber hinaus wurde gefunden, daß sich die Innenpräparation für die o.g. Nahrungsmittelhüllen auch für Schmal- und Kranzhüllen eignet, die beispielsweise für geräucherte Fleischwürste und grobe Mettwürste eingesetzt werden.The invention relates to a tubular food casing based on cellulose with a coating present on its inner surface to improve the peelability of the casing from the contents and to the use of the food casing. In particular, the invention relates to peeler casings which are used for sausage meat and scalded sausage types and which provide very good peelability on automatic peeling machines which operate at high speed. In addition, it was found that the internal preparation for the above. Food casings are also suitable for narrow casings and wreath casings, which are used, for example, for smoked meat sausages and coarse meat sausages.
Hüllen der gattungsgemäßen Art sind bereits aus der EP-A-109 611 bekannt und besitzen auf ihrer Innenseite einen Überzug aus einer Mischung aus einem wasserlöslichen Celluloseäther, einem Wachs und einem Öl. Eine aus der DE-A-34 47 026 bekannte Hülle gleicher Gattung enthält in einem innenseitig aufgebrachten Überzug neben einer Chrom-Fettsäure-Komplexverbindung und einem Dialkylpolysiloxan zusätzlich ebenfalls Celluloseäther und Wachs. Alle bekannten Rezepturen zur Verbesserung der Abschälbarkeit besitzen relativ komplizierte Zusammensetzungen, und sie lassen, insbesondere bei problematischen Füllgütern, im Hinblick auf ihre Wirksamkeit noch zu wünschen übrig.Cases of the generic type are already known from EP-A-109 611 and have on their inside a coating of a mixture of a water-soluble cellulose ether, a wax and an oil. A casing of the same type known from DE-A-34 47 026 also contains cellulose ether and wax in addition to a chromium-fatty acid complex compound and a dialkylpolysiloxane in an internally applied coating. All known formulations for improving the peelability have relatively complicated compositions, and they leave something to be desired in terms of their effectiveness, particularly in the case of problematic filling goods.
Neben den nicht-eßbaren Nahrungsmittelhüllen auf Basis von Cellulose sind auch eßbare Hüllen auf Basis von Polysacchariden, wie Alginsäure oder Alginat, Chitosan, Pectin, Stärke, Furcellaran, Carrageenan und Agar, bekannt (EP-A 0 400 484). In heißem Wasser lösen sich diese Hüllen auf. Durch eine ein- oder beidseitig aufgebrachte Schicht aus einem wasserlöslichen Protein kann die eßbare Hülle heißsiegelfähig gemacht werden.In addition to the non-edible food casings based on cellulose, edible casings based on polysaccharides such as alginic acid or alginate, chitosan, pectin, starch, furcellaran, carrageenan and agar are also known (EP-A 0 400 484). These shells dissolve in hot water. The edible casing can be made heat-sealable by a layer of water-soluble protein applied on one or both sides.
Eßbare Wursthüllen werden jedoch in der Regel auf Kollagenbasis hergestellt. Beim Kochen der Wurst soll die Hülle möglichst im selben Maß schrumpfen wie der Inhalt. Um eine solche schrumpffähige Hülle herzustellen, wurde dem zerkleinerten und zu einer Paste vermahlenen Kollagen Natriumalginat zugemischt, die Mischung dann extrudiert und in einer wäßrigen Metallsalzlösung ausgehärtet (DE-A 14 92 711).However, edible sausage casings are usually made on a collagen basis. When cooking the sausage, the casing should shrink to the same extent as the content. In order to produce such a shrinkable casing, sodium minginate, which had been comminuted and ground into a paste, was mixed in, the mixture was then extruded and cured in an aqueous metal salt solution (DE-A 14 92 711).
Aufgabe der vorliegenden Erfindung war es, eine Nahrungsmittelhülle mit einer Innenpräparation (Innenbeschichtung) anzugeben, bei der die Beschichtungszusammensetzung aus möglichst wenig Einzelkomponenten aufgebaut ist und die trotzdem ein breites Wirkungsspektrum besitzt, was ihre Abschälbarkeit von verschiedenen Füllgütern betrifft.It was an object of the present invention to provide a food casing with an inner preparation (inner coating) in which the coating composition is made up of as few individual components as possible and which nevertheless has a broad spectrum of activity in terms of its peelability from different filling goods.
Gelöst wird diese Aufgabe durch eine Nahrungsmittelhülle der eingangs genannten Gattung, deren Kennzeichenmerkmal darin besteht, daß der Überzug Alginate, Alginsäure, Chitosane oder eine Kombination von diesen enthält.This object is achieved by a food casing of the type mentioned at the outset, the distinguishing feature of which is that the coating contains alginates, alginic acid, chitosans or a combination of these.
Bei der erfindungsgemäßen Nahrungsmittelhülle handelt es sich bevorzugt um eine künstliche Wursthülle, insbesondere um eine wässerungsfreie Wursthülle, die geeignet ist für das Brühen, Räuchern und automatische Schälen von kleinen Brühwürstchen. Der spezielle Überzug auf der Innenseite zeigt verringerte Haftung zwischen der Innenwand der Hülle und dem bevorzugt für klein- und mittelkalibrige Hüllen und Kranzdarm aber auch für großkalibrige Hüllen typischen Füllgut, insbesondere wenn das Füllgut ein Wurstbrät ist für Brühwürstchen, wie Frankfurter Würstchen, oder wie Jagdwurst, Bierschinken, Fleischwurst, Mortadella, Gelbwurst oder Lyoner, aber auch für Räucherwurst und Rohwurst wie grobe Mettwurst, wobei letztere insbesondere in gekrümmten oder ringförmigen Hüllen aus Cellulose ohne Faserverstärkung hergestellt wird.The food casing according to the invention is preferably an artificial sausage casing, in particular a water-free sausage casing, which is suitable for scalding, smoking and automatically peeling small scalded sausages. The special coating on the inside shows reduced adhesion between the inner wall of the casing and the filling material, which is typical for small and medium-sized casings and coronary but also for large-caliber casings, especially when the filling material is a sausage meat for cooked sausages, such as frankfurter sausages, or like hunting sausages , Ham, meat sausage, mortadella, yellow sausage or Lyoner, but also for smoked sausage and raw sausage such as coarse mettwurst, the latter being produced in particular in curved or ring-shaped casings made of cellulose without fiber reinforcement.
Die Nahrungsmittelhülle besteht aus einem Trägerschlauch Basis von Cellulose und dem zur Verbesserung der Abschälbarkeit der Hülle vom Füllgut vorgesehenen Überzug auf ihrer Innenwand.The food casing consists of a carrier tube based on cellulose and the coating provided on its inner wall to improve the peelability of the casing from the filling material.
Das Basismaterial für den Trägerschlauch ist Cellulose (Zellglas, regenerierte Cellulose, Cellulosehydrat) und wird auf übliche Weise als nahtloser Schlauch durch Koagulation und Regenerieren vorzugsweise aus Viskoselösung hergestellt. Es ist auch möglich, Schläuche mit einer Klebenaht zu verwenden, die durch Falten einer Bahn und Verbinden der Ränder hergestellt werden (EP-A-0 050 702, EP-A-0 058 240). Für die Verwendung der Hülle zur Herstellung von Würsten vom Brühwurst-Typ großen Kalibers verwendet man einen Trägerschlauch aus Cellulose mit einer Faserverstärkung, die beispielsweise in Form einer Papierbahn in der Wandung des Trägerschlauchs eingebettet ist. Zur Herstellung von gekrümmten oder ringförmigen Würsten, wie Rohwürste, insbesondere grobe Mettwürste, verwendet man Trägerschläuche in gekrümmter oder in abgerundeter Ringform, sogenannte Kranzdärme, welche keine Faserverstärkung aufweisen. Die Krümmung wird beispielsweise durch einseitige Verdehnung des Schlauches bei seiner Herstellung erzeugt, es sind aber auch andere Verfahren bekannt (US-A-2,136,566, US-A-2,925,621, US-A-3,679,435, EP-A-0 050 702).The base material for the carrier tube is cellulose (cellophane, regenerated cellulose, cellulose hydrate) and is produced in the usual way as a seamless tube by coagulation and regeneration, preferably from viscose solution. It is also possible to use hoses with an adhesive seam, which are produced by folding a web and connecting the edges (EP-A-0 050 702, EP-A-0 058 240). A carrier tube made of cellulose with a fiber reinforcement, which is embedded, for example, in the form of a paper web in the wall of the carrier tube, is used for the use of the casing for producing sausages of the large caliber type of cooked sausage. For the production of curved or ring-shaped sausages, such as raw sausages, in particular coarse sausages, carrier tubes with a curved or rounded ring shape, so-called ring casings, which have no fiber reinforcement, are used. The curvature is produced, for example, by one-sided expansion of the hose during its manufacture, but other methods are also known (US Pat. Nos. 2,136,566, 2,925,621, 3,679,435, 050502 EP).
Die Nahrungsmittelhülle kann als flachgelegter Schlauch zum Füllen mit Füllgut eingesetzt werden. Es lassen sich auch geraffte Schlauchhüllen, sog. Raupen, herstellen, wobei man übliche Raffvorrichtungen (US-A-3,988,804) einsetzt. Hierbei hat sich gezeigt, daß mit der Innenbeschichtung nicht nur eine verbesserte Trennwirkung zwischen Füllgut und Hülleninnenwand erzielt wird, sondern daß sich auch noch zusätzliche Vorteile beim Aufwickeln, Lagern, Raffen und Verarbeiten ergeben. So sorgt die Innenbeschichtung dafür, daß die auf einer Rolle aufgewickelten Schläuche nicht haften oder verkleben. Auch Hüllenabschnitte verkleben bei längerer Lagerung nicht und lassen sich vor dem Befüllen mit Wurstbrät, insbesondere auf automatischen Füllmaschinen, problemlos öffnen. Ferner sind die Schläuche besonders gleitfähig und weich und lassen sich deshalb problemlos raffen.The food casing can be used as a flat tube for filling with contents. Ruched tubular casings, so-called caterpillars, can also be produced, using conventional gathering devices (US Pat. No. 3,988,804). It has been shown here that the inner coating not only achieves an improved separation effect between the filling material and the inner wall of the casing, but that there are also additional advantages when winding, storing, gathering and processing. The inner coating ensures that the hoses wound on a roll do not stick or stick. Even casing sections do not stick together during long storage and can be opened without problems before filling with sausage meat, especially on automatic filling machines. Furthermore, the hoses are particularly slippery and soft and can therefore be gathered easily.
Der Überzug enthält erfindungsgemäß Alginate, Alginsäure und/oder Chitosane. Alginate sind Salze der Alginsäure, insbesondere Alkali- oder Erdalkalisalze. Alginsäure selbst ist ein farbloses, Carboxylgruppen enthaltendes Polysaccharid mit einem mittleren Molekulargewicht zwischen 100 000 und 240 000. Chemisch besteht Alginsäure aus 1,4-glykosidisch verknüpften D-Mannuronsäureeinheiten mit gelegentlichen Einschüben von α-glykosidisch gebundenen L-Guluronsäureeinheiten. Alginsäure als solche ist ein Naturprodukt und findet sich in beträchtlichen Mengen in den Braunalgen des Meeres.According to the invention, the coating contains alginates, alginic acid and / or chitosans. Alginates are salts of alginic acid, especially alkali or alkaline earth salts. Alginic acid itself is a colorless, carboxyl group-containing polysaccharide with an average molecular weight between 100,000 and 240,000. Chemically, alginic acid consists of 1,4-glycosidically linked D-mannuronic acid units with occasional insertions of α-glycosidically bound L-guluronic acid units. Alginic acid as such is a natural product and finds in abundance in the brown algae of the sea.
Die Chitosane sind eine Verbindungsgruppe, die sich von natürlich vorkommendem Chitin ableitet. Sie entstehen durch Desacetylierung und teilweise Depolymerisierung von Chitin mit Hilfe von starken Alkalien. Chemisch handelt es sich um β-glykosidisch gebundene Poly-N-acetylglucosamine, deren Acetylgruppen durch die Einwirkung der starken Alkalien in mehr oder weniger großem Umfang verseift sind. Die Chitosane besitzen ein mittleres Molekulargewicht von etwa 400 000.The chitosans are a compound group that is derived from naturally occurring chitin. They result from deacetylation and partial depolymerization of chitin with the help of strong alkalis. Chemically, they are β-glycosidically bound poly-N-acetylglucosamines, the acetyl groups of which are saponified to a greater or lesser extent by the action of the strong alkalis. The chitosans have an average molecular weight of approximately 400,000.
Die Auftragsmenge der hydrophilen Wirkkomponente/n (Alginat, Alginsäure, Chitosan) liegt erfindungsgemäß im Bereich von 5 bis 100 mg/m², vorzugsweise im Bereich von 10 bis 70 mg/m², bezogen auf das Trockengewicht der Hülle. Der Auftrag erfolgt erfindungsgemäß aus einer wässrigen Überzugszusammensetzung mit einer Konzentration der Wirkkomponenten im Bereich von 0,5 bis 4,0 Gew.-%, vorzugsweise im Bereich von 1 bis 3 Gew.-%, bezogen auf das Gesamtgewicht der Präparationslösung.The application amount of the hydrophilic active component (s) (alginate, alginic acid, chitosan) is, according to the invention, in the range from 5 to 100 mg / m², preferably in the range from 10 to 70 mg / m², based on the dry weight of the casing. According to the invention, the application takes place from an aqueous coating composition with a concentration of the active components in the range from 0.5 to 4.0% by weight, preferably in the range from 1 to 3% by weight, based on the total weight of the preparation solution.
Der Überzug der erfindungsgemäßen Nahrungsmittelhülle enthält bevorzugt noch weitere Gleit-, Raffhilfs- und Trennmittel als Zuschlagstoffe. Hierzu eignen sich insbesondere die verschiedensten Öle, z.B. natürliche Öle wie Olivenöl oder Rapsöl oder synthetische Mono-, Di- und Triglyceride, Paraffinöle, Siliconöle und/oder Wachse. Bevorzugte Wachse sind Säurewachse auf Basis von Rohmontanwachs. Sie sind beispielsweise erhältlich unter der Bezeichnung Hoechst-Wachs, Typ E, X22, F, KP 301, KPS, KSL, KSS, KST, KFO, U, BJ oder RT. Bevorzugt wird der Typ KPS eingesetzt, ein Äthandiolester der Montansäure. Die Zuschlagstoffe werden der wässrigen Überzugszusammensetzung in Mengen von 0,5 bis 30 Gew-%, vorzugsweise von 1 bis 5 Gew-%, bezogen auf das Gesamtgewicht der wässrigen Präparationslösung zugegeben.The coating of the food casing according to the invention preferably contains further lubricants, gathering aids and release agents as additives. A wide variety of oils are particularly suitable for this purpose, for example natural oils such as olive oil or rapeseed oil or synthetic mono-, di- and triglycerides, paraffin oils, silicone oils and / or Waxes. Preferred waxes are acid waxes based on raw montan wax. They are available, for example, under the name Hoechst-Wachs, type E, X22, F, KP 301, KPS, KSL, KSS, KST, KFO, U, BJ or RT. The KPS type is preferably used, an ethanediol ester of montanic acid. The additives are added to the aqueous coating composition in amounts of 0.5 to 30% by weight, preferably 1 to 5% by weight, based on the total weight of the aqueous preparation solution.
Zum Emulgieren der Zuschlagstoffe können die üblichen Emulgatoren, z.B. Alkylsulfonate, Alkylarylsulfonate, Alkylsulfate, Alkylarylsulfate oder nichtionogene Emulgatoren wie äthoxylierte Alkohole oder Amine zugegeben werden.To emulsify the additives, the usual emulsifiers, e.g. Alkyl sulfonates, alkyl aryl sulfonates, alkyl sulfates, alkyl aryl sulfates or nonionic emulsifiers such as ethoxylated alcohols or amines are added.
Auch Monofettsäureester oder mehrwertige Alkohole wie Sorbitmonoester oder Alkandiole, wie 1,2-Propandiol, sind als Emulgatoren geeignet. Die Emulgatoren werden in Mengen von 5 bis 50 Gew-%, bezogen auf das Gewicht der Präparationslösung, angewandt. Es hat sich überraschenderweise gezeigt, daß insbesondere die Alkandiole, und hier bevorzugt 1,2-Propandiol, einen zusätzlichen stabilisierenden Effekt auf die Hüllen, insbesondere auf die grafften Hüllen (Raupen) ausüben, bevorzugt auf solche, welche aus einer labileren Grundware aufgebaut sind.Monofatty acid esters or polyhydric alcohols such as sorbitol monoesters or alkanediols such as 1,2-propanediol are also suitable as emulsifiers. The emulsifiers are used in amounts of 5 to 50% by weight, based on the weight of the preparation solution. It has surprisingly been found that in particular the alkanediols, and here preferably 1,2-propanediol, have an additional stabilizing effect on the casings, in particular on the graffed casings (caterpillars), preferably on those which are made up of a more labile basic material.
Als besonders geeignet für Schäldarmtypen haben sich Präparationslösungen erwiesen, die neben Alginat, Alginsäure und/oder Chitosan sowohl ein Öl als auch ein Wachs enthielten.Preparation solutions which, in addition to alginate, alginic acid and / or chitosan, contain both an oil and a wax have proven to be particularly suitable for types of peelings.
Die erfindungsgemäße Nahrungsmittelhülle wird hergestellt nach den üblichen Verfahren zur Herstellung von Nahrungsmittelhüllen, insbesondere Wursthüllen, auf Basis von Cellulose, die sich vom Füllgut, insbesondere von der Wurstmasse, leicht abschälen lassen.The food casing according to the invention is produced by the usual methods for producing food casings, in particular sausage casings, based on cellulose, which can be easily peeled off from the filling, in particular from the sausage mass.
Der Auftrag der Innenbeschichtung auf die Innenseite der Schlauchhülle erfolgt auf übliche Weise, beispielsweise durch Einfüllen einer Beschichtungsflüssigkeit in die Schlauchhülle (GB-A-1 201 830, US-A-2,901,358, DE-A-28 01 038, DE-C-30 12 250) oder durch Aufsprühen der Beschichtungsflüssigkeit in die Schlauchhülle während des Raffprozesses, z.B. durch den hohlen Raffdorn (US-A-3,451,827). Die Auftragstemperatur ist gewöhnlich gleich der Umgebungstemperatur, d.h. sie liegt bei etwa 15 bis 30°C.The inner coating is applied to the inside of the tubular casing in the usual way, for example by pouring a coating liquid into the tubular casing (GB-A-1 201 830, US-A-2,901,358, DE-A-28 01 038, DE-C-30 12 250) or by spraying the coating liquid into the tubular casing during the shirring process, e.g. through the hollow shirthorn (US-A-3,451,827). The application temperature is usually equal to the ambient temperature, i.e. it is around 15 to 30 ° C.
Das Einfüllen der Beschichtungsflüssigkeit in die Schlauchhülle erfolgt zweckmässigerweise bereits bei der Herstellung der Schlauchhülle, z.B. nach der Fällung des Cellulosehydrat-Gels aus Viskose und vor der Trocknung.The filling of the coating liquid into the tubular casing expediently takes place during the manufacture of the tubular casing, for example after the cellulose hydrate gel has been precipitated from viscose and before drying.
Wenn die erfindungsgemäßen Wursthüllen bei ihrem bestimmungsgemäßen Einsatzzweck mit Wurstbrät befüllt, gebrüht und geräuchert werden, lassen sich die Hüllen auf automatischen Schälvorrichtungen völlig problemlos entfernen. Der erfindungsgemäße Überzug hat sich sowohl bei Cellulosehüllen als auch bei faserverstärkten Cellulosehüllen in der Praxis bewährt.If the sausage casings according to the invention are filled with sausage meat, scalded and smoked during their intended use, the casings can be removed completely easily on automatic peeling devices. The coating according to the invention has proven itself in practice both in the case of cellulose casings and in the case of fiber-reinforced cellulose casings.
